Filtered W+jet multijet events (2->2 process) using a electron and muon filters. PDF: LHAPDF6:NNPDF23_lo_as_0130_qed. The sample was created using the Pythia8 tune Tune:pp = 14, similar to ATLAS. The sample was created for ATLAS studies of dijet+lepton event topologies.

EM filters

Events contain at least one final state electron or muon. The leptons are isolated to make sure there is no hadronic activity around. This was done by using a cone of 0.2 around the lepton, and by requiring that the lepton carries at least 90% of energy of the 0.2 cone in eta and phi. pT cut on isolated leptons is 40 GeV. In addition, fake lepton and muon rates were simulated. It is assumed that an antiKT4 jet with less than 10 numbers of constituents have 10% chance to be electron, and 1% chance to be a muon. Such fake leptons were put at the end of the event records. The particles that were used for fake leptons were subtracted from the original event record.

How to use weights

This is weighted events to obtain good statistics up to very large pT. This feature is set via PhaseSpace:bias2Selection and PhaseSpace:bias2SelectionPow = 5.0. Use event weights to obtain correct pT distribution.

Slimmed as

Particle records are slimmed (all stable with pT>0.3 GeV) and (PID=5 || PID=6) or PID>22 && PID<38) or PID>10 && PID<17).
